color - How can I achieve an iridescent/metallic/holographic effect in raster editors?



I understand this effect can be achieved in 3D rendering programs, but I also believe that it can be achieved through a raster editor like Photoshop. I work in Affinity Photo on iPad, so I’ll need to be able to translate any workflow into there. I’ve tried liquifying brush strokes, and it gets close, but doesn’t quite accomplish what I’m going for. Other threads I’ve researched recommend normal/gradient maps, but that seems like a lot of work for still not quite what I’m trying to do. Whatever it is I need to do seems to be reliant upon color palette and texture. Have been searching forever for an answer!


Two more instances of this effect:
